GreenGuard®: Built to Protect

Kingspan GreenGuard® delivers the confidence of proven XPS insulation, trusted in thousands of projects across North America. With an R-value of 5 per inch, it provides reliable thermal efficiency for walls, roofs, and below-grade applications, helping meet energy goals without compromising design.

Engineered with a tight closed-cell structure, GreenGuard® offers resistance to water absorption. This added protection preserves insulating power, prevents moisture-related damage, and ensures long-term durability even in demanding conditions. From foundations and exterior walls to protected roof assemblies and plaza decks, GreenGuard® is built to perform where strength and resilience matter most.

Available in the U.S. and Canada; product details may vary in other regions.
